Itiis jfurther' desired to provide a lIIbI'l-V cation of a simple and substantial constructionespeeially designed to insure heating oflthe lubricant-in the immediate vicinity of thejfloweeontr'olling valve, the invention 7 contemplating such an arrangement of parts 151s Will permit of theobj'serva-tion ofth'e rate at'vvhich the liquefied lubricating material, V
